A church hymn is a type of religious song that is sung in a church setting. The term 'church hymn' can refer to both traditional hymns and modern worship songs. Two examples of church hymns are 'CANTICLE' and 'Rock of Ages'. 'CANTICLE' is a term used to describe a song or poem from the Bible, usually taken from the Old Testament. 'Rock of Ages' is a popular Christian hymn written by Augustus Montague Toplady in 1763. It is often sung in churches today as a reminder of God's faithfulness and power.
